Description

[Detailed description of the invention] [Technical field of invention] This invention can be used in home kitchens, restaurants, and hotels.

The present invention relates to a processing device for kitchen waste generated in the kitchens of hotels and the like, and more specifically to a waste processing device that hygienically removes moisture from kitchen waste and facilitates its handling.

[Prior art]

Conventionally, this type of equipment used centrifugal separation or screw presses to remove water after crushing kitchen waste, but in both cases, the screen of the centrifugal separator or screw press was often clogged with rice grains, resulting in poor dewatering performance. It was impractical because it deteriorated significantly.

Therefore, in Japan, kitchen waste is generally put into plastic bags or plastic containers without being processed in any way, and is stored at each place where it is generated until the waste is collected by local governments. There were hygiene problems such as a bad odor.

In addition, kitchen waste has a high moisture content and is bulky, making it inconvenient to handle and resulting in high transportation costs and high final disposal costs such as incineration.

[Summary of the invention]

This departure F! A was made to solve the above problem, and includes a container for storing kitchen waste, a gas supply means for circulating and supplying gas to this container, a heating means for heating the gas, and a container for storing kitchen waste. , a gas circulation path formed by a gas supply means and a conduit communicating between the heating means, and the conduit.

By providing a branch path for taking out a portion of the gas to the outside of the gas circulation path, high-temperature gas is applied to the kitchen waste to remove moisture contained in the kitchen waste, making the kitchen waste sanitary and easy to handle. The aim is to provide a practical kitchen waste processing device.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
Figure 92 is a conceptual diagram showing an embodiment of the present invention. In Figure 92, (1) is a container for storing kitchen waste, and (2) is a gas supply means for circulating and supplying gas to this container. A blower, (3) is a heating means for heating the gas, that is, a heater in this example, and (4) is a conduit that communicates between the container +1), the blower (2), and the heater (3), and the container (1). A gas circulation path is formed by the blower (2), heater (3), and conduit (4). '(5) is the outlet side of the container (liquid) and the heater (
3) is provided in the conduit (4) connecting the inlet side, and takes out a part of the gas to the outside of the gas circulation path; (6) is a sink.

(7) is the drain pipe attached to this sink 6), (8)
) is the water seal part of this drain pipe (7). In this example, the branch path (5) is connected to the drain pipe (7) of the sink 6).

Next, the operation will be explained. When a predetermined amount of kitchen waste is placed in the container (1), the blower (2) is operated, and the heater (3) is turned on, the gas (initially air) in the circulation path will...

After being heated and raised in temperature by a heater (3) as shown by the arrow.

After coming into contact with the kitchen waste in the container (1) and heating it to raise its temperature and evaporating at least a portion of the moisture in the kitchen waste, it is circulated and supplied again to the heater (3) by the blower (2) as described above. The heating-evaporation process is repeated. At this time, the temperature of the gas circulating in the circulation path gradually rises, and its volume increases.

In addition, steam is generated in proportion to the amount of water evaporated from the kitchen waste.

This also increases the volume of gas in the circulation path. The increased volume of gas is discharged into the drain pipe (7) of 6) which flows through the branch (5). Drain pipe (7
) is normally equal to atmospheric pressure, so the pressure of the gas in the circulation path is also balanced with the pressure in the drain pipe (7).

It remains essentially at atmospheric pressure.

The gas in the circulation path is initially air, but as the temperature of the kitchen waste increases over the course of two hours, water vapor is generated one after another, so it is gradually replaced by the air mineral water vapor that was initially in the circulation path, and finally Substantially only water vapor circulates in the circulation path. Then, an amount of water vapor corresponding to the new water vapor that continues to be generated one after another flows into the branch path (5
) and into the drain pipe (7) where it condenses into water.

In this way, the moisture in the kitchen waste is removed and the kitchen waste is dried, but when the kitchen waste has sufficiently dried and the amount of water vapor generated from the kitchen waste decreases, the temperature of the kitchen waste begins to rise significantly. Turn off the heater (3), and when the temperature of the kitchen waste has dropped sufficiently, stop the blower (2) and take out the dried kitchen waste.

FIG. 2 is a conceptual diagram showing another embodiment of the present invention, in which the blower (2) is moved to the downstream side from the installation position of the branch passage (5), and a reservoir for condensing water vapor is installed in the branch passage (5). This embodiment is the same as the embodiment shown in FIG. 1, except that a condenser O1l is newly provided. The operation is also similar. Since the condenser αυ condenses the water vapor pushed out to the branch path (5), there is almost no pressure rise in the circulation path 1 branch path (5) and the drain pipe (7), and the water vapor is smoothly discharged. It will be held on
There is no problem of kitchen garbage odor being released due to water vapor leakage.

Further, since the temperature of the drain pipe (7) does not rise, there is no need to worry about deformation even if a vinyl chloride pipe is used for the drain pipe (7). Also, connect the blower (2) to the branch path (5).
Although the mounting position is moved to the downstream side, the same effect as in the embodiment shown in FIG. 1 can be obtained in this case as well.

FIG. 3 is a conceptual diagram showing an example of a container (1) according to an embodiment of the present invention. The reeds and lid Qυ of the container (1) also serve as the bottom plate of the cut-out part of the sink 6).

In this embodiment, a basket (c) is used to take in and take out the kitchen waste tA from the input/output port I23 provided at the top of the container (1), but other embodiments shown in FIG. The outlet for the kitchen waste (c) may be provided at the bottom of the container, as shown in FIG. In Figure 4, C1υ is the input port for kitchen waste.

0 indicates the garbage disposal or exit, and the other symbols are the same as those shown in FIGS. 1 to 3. In this embodiment, there is no need to use a basket (c) as in the example in Fig. 3, and once the drying is completed, the shelf Q4 and the outlet 0 are opened as indicated by the dotted arrow □ and the drying process is carried out. The dried kitchen waste C1 is taken out from the bottom of the container αυ.8 The dried kitchen waste obtained in the above manner has been sufficiently dehydrated and its weight has been significantly reduced.

Even if you leave it as is, there will be no odor.

Easy to handle and hygienic.

In addition, kitchen waste (
b) Evaporate the water in the water to generate water vapor.

Only the newly generated water vapor is taken out of the system through the branch path (5) connected to the circulation path.

Only the circulating gas needs to be heated, which is energy-saving. Furthermore, in the embodiments shown in FIGS. 3 and 4, the kitchen waste basket input port (c) and 0υ are attached to the sink 6), making it convenient to handle the kitchen waste basket. moreover.

The drain of the kitchen waste (C) and the water vapor generated from the kitchen waste (1) are drained downstream of the water seal part (8) of the drain pipe (7) of 6), which prevents odor from leaking to the surrounding area. It's very hygienic.
